Hello, my name is Aravind Sundararajan. I made and maintain this site.
I am a PhD graduate of the University of Tennessee.
My graduate research was on the neural control of gait and general behavioral tasks;
however, I also enjoy various projects in my free time including, but not limited to:
- soldering, board level repair, pcb design in kiCad
- game design, music, and art
- linguistics
- webdesign and networking
- exploring optimization problems, game theory, game AI design
- Check out my open source projects at my Github
- Contact me at: aravind.sundararajan@protonmail.com
My proposal for the future:
For clinicians and researchers to understand gait and other behavioral tasks, they rely on expensive motion capture systems.
Qualisys.
Vicon.
Motion Analysis.
Xsens.
Optitrack.
NDI.
Phoenix Technologies, Inc.
myoMOTION.
DARI Motion.
All of these providers offer solutions with varying degrees of clinical, commercial or research application.
Generally, these providers offer motion capture solutions that use some combination of reflective markers, real video analysis, and inertial measurement units (IMU).
Despite the closing gap in accuracy between IMU and conventional reflective marker-based inverse kinematics to perform motion analysis, products on the market can still remain tens or even hundreds of thousands of USD.
What I want to do is design an affordable, modular, and open-source motion capture platform that uses IMU and is able to capture arbitrary motions of arbitrary multibody systems.
Clinical motion analysis is not a tool that should be reserved to researchers, wealthy sports teams, Hollywood, or very few clinicians that can afford commercial systems; it's a powerful tool that will prove invaluable in rehabilitation and diagnosis, especially as we make continued strides in making it affordable.
Personally, I just happen to sit in this very unique intersection where I have an expertise in programming, dynamics, biomechanics, electrical engineering, 3D printing, prototyping, and hardware/product development, so this is certainly a reality I hope to achieve in the next stage of my life.

Feasible Sets Analysis of Musculoskeletal Systems:
I have experience with 3D printing, openSCAD, freeCAD, and KiCad.
I enjoy soldering and hot air rework, too.
I make games and mods in my free time too:
